Re: 6 volt jump starter
I'm interested in following this because I had the same question. I've used the NOCO Genius Boost Sport GB20 (says 12 volt on it). I didn't seem to have any problems but I'm not sure it's the correct thing to use.

Re: 6 volt jump starter
As long as you have no lights on a 12V jump box won't hurt anything. DISCONNECT it as soon as it starts. JMO
Paul in CT I've done it. |

Re: 6 volt jump starter
Like the others have said, if the reason you are looking is to jump your A, you don't need 6volts.

Re: 6 volt jump starter
I agree 100% but this could launch us once again into a discussion on ignition timing. If you're going to crank it, make sure the timing is FULLY RETARDED. I subscribe to the timing technique where the timing is done at TDC with the steering column lever down a couple of notches. That means that when the lever is all the way up, the ignition will fire AFTER TDC, making a kick back (and broken wrist), impossible.

Re: 6 volt jump starter
Thanks to everyone. Hand cranking with the possibility of "kick back" brings back memories of the old Harleys before electric starters!!!!

Re: 6 volt jump starter
I had a 1964 Harley duoglide , it had the spark on the left handle bar grip. It could pick you up and throw you off the kick starter if you failed to retard the spark. I wish that I had kept it .

Re: 6 volt jump starter
I run 6V positive ground alternators. What will a 12 Volt jump do to them?

Re: 6 volt jump starter
I also jump started 6V batteries with 12V untill a few years ago I did it on a 1944 Willys and the battery exploded !! No one hurt but the bakelite parts still stick in the isolation of the ceiling !

Re: 6 volt jump starter
I used to drive a cushmann at work - all steel golf cart utility cart. Had a bank of 6 12V batteries under the plywood bottomed seats. one day i was driving around and lost power all of a sudden. No biggie still had reverse so was backing my way towards the maint shop (some reason when the batteries ran low most of the time you could reverse but not forward - no idea why) got about 3/4 way there and then it wouldnt move at all. I kept tryign to get life into the thing by going forward and reverse till i felt and it lifted me off the seat a few inches one of the batteries explode under my butt. Bad when its loud with earpugs in. I jumped off in a hurry to discovera waterfall of battery acid raining down under it. Thankfully i was just fine - just more shocked than anything. Concrete was permanently discolored where the acid was haha.

Re: 6 volt jump starter
Why not just give it a push?
They start right up. Usually with two or three feet. Back in the late fifties and early sixties it was common. Enjoy. |

Re: 6 volt jump starter
The cart repair guys seem to think the battery internally shorted hence massive amp draw. Could have been the case in your instance too.
